The Epicure's Almanac or Diary of Good Living
June 9th : COMMON VINEGAR
Boil three quarters of a pound of coarse moist sugar in a gallon of water, for half an hour, skimming it well all the time; let it cool, and put in a table-spoonful of yeast. Next day pour it into a stone bottle, and add an ounce of cream of tartar. Let it be exposed to the sun until the heat has turned it to vinegar.
